Hi,

I own a 1983 Pontiac Firebird (Trans Am) with a 5.0 305.

When I bought the car, it has been smoking blue smoke.

It only smokes it at operating temperatures.

I don't think it's been overheated ever, it was sitting for 20 years in a barn, and is a project car.

The owner used to start it up every year or so but never drove it really.

What do I do?

Rebuild the engine.

Your burning oil.

305’s are notorious for doing that.

Valve seats are worn out and it sure didn’t help it being started only once a year for 20 years.

Keep us posted friend.

If you replace the heads you're replacing the valve seats because it would be a fully rebuilt head.
